Open the SnapStream app. You should see a PIN. This will be used to pair your FireTV stick to your SnapStream system.

On your computer or phone, open the SnapStream web interface

Navigate to Admin -> Actions -> View Set-Top Boxes -> Add Set-Top Box

Enter the PIN from your FireTV Stick to pair it. The SnapStream app should connect automatically and show the SnapStream Library. (If necessary, it may also perform an update to the app. This should complete automatically.)

This FireTV Stick should remain paired to the SnapStream server until it is removed via the SnapStream web interface
